Patients after abdominal operation with delayed-ambulation may often lead to develop post-operative complications including pneumonia, intestinal obstruction, pressure sore, decreased recovery rate, and increased hospital cost. Therefore the accomplished goal of this improvement proposal is to decrease the delayed-ambulation rate from 69% to 39%. Through action team interviewing with these delayed-ambulation patients, the mainly influence factors were wound pain and ignorance of how post-operative ambulation be performed. Our team drew up a flow chart for post-operative patients performing early ambulation with the helps of health education materials and standard operating procedure of nursing care. After operation, we executed pain evaluation and education of pain management. Practicably, we helped the patients to get out of bed. Eventually, the rate of delayed-ambulation cases decreased greatly to 3.3%. Obviously, this program may effectively solve the problems of post-operative delayed-ambulation patients.
